PVDF & ECTFE Engineering PlasticPVDF & ECTFE

High Performance Fluropolymer Plastics


A high-quality fluoropolymer material (chemical name is polyvinylidene fluoride) with higher strength, pressure resistance and dimensional stability than PTFE.

ECTFE (Halar®)

A very pure fluoropolymer material (chemical name is ethylen-chlortrifluorethylene) with excellent corrosion and weather resistance, outstanding fire-safe properties and a particularly smooth surface. ECTFE also has permeation resistance to oxygen, carbon dioxide, chlorine gas and hydrochloric acid that is 10 to 100 times better than PTFE.


The machining of polypropylene is uncomplicated, provided the component tolerances allow for polypropylene’s relatively high co-efficient of thermal expansion and tensile elongation values. Full machining instructions can be supplied on request.

Chemical Resistance


Very resistant to acids, oxidising agents, halogens, alcohols, chlorinated solvents, aliphatic hydrocarbons and fuels. At high temperature, it is not resistant to alkaline solutions or amines.


Resistant to strong mineral and oxidizing acids, alkalis, liquid oxygen and organic solvents. It is attacked by molten metallic sodium and potassium.
